Buy Bonus Slots Explained — Is It Worth It?

Michael Madden · April 2026

Buy Bonus (also called Feature Buy or Bonus Buy) is a feature on compatible slots that lets you purchase the bonus round directly, skipping base game spins. The cost is typically 50–100 times your stake.

How Buy Bonus Works

When available, a "Buy Bonus" button appears in the game interface. Clicking it deducts the purchase cost directly from your balance and immediately triggers the bonus round. The cost reflects the statistical probability of triggering the bonus organically multiplied by your stake.

Is Buy Bonus Worth It?

Mathematically, Buy Bonus gives you the same RTP as triggering the bonus through base game play — you are paying for immediacy and certainty, not improved odds. The advantage is time efficiency: instead of potentially 200 spins waiting for a bonus trigger, you get it immediately.

Important for bonus players: Buy Bonus is typically disabled or restricted when you have an active welcome bonus or free spins. Using Buy Bonus with active bonus funds may forfeit the bonus. Always check T&Cs before purchasing.

Best Buy Bonus Slots

Gates of Olympus (Pragmatic Play) — 100x stake buy-in for the tumbling reels bonus. Sweet Bonanza — 100x stake for the candy scatter pays bonus. Wanted Dead or a Wild (Hacksaw) — multiple bonus levels available for purchase at different price points.
